Hands-on learning in a remote laboratory environment.
This Journal of Chemical Education Article by Deon T. Miles and William G. Wells of the Department of Chemistry, Sewanee: The University of the South describes a homemade kit with at home, hands on laboratory experiments in spectroscopy and chromatography. The paper and supporting information describe both hands on (chromatography and spectroscopy) and virtual experiments (IR, NMR, GC-MS and cyclic voltammetry data provided) for a semester course in Instrumental Analysis. The article is very thorough and lists every item that is sent home with students, along with its cost and also provides experimental handouts for students. If you are looking for some at home or virtual experiments, check it out!

*An experimental procedure is provided and data was obtained from Liotta, L. J.; James-Pederson, M. Identification of an Unknown Compound by Combined Use of IR, 1H NMR, 13C NMR, and Mass Spectrometry: A Real-Life Experience in Structure Determination. J. Chem. Educ. 2008, 85 (6), 832– 833, DOI: 10.1021/ed085p832
**This experiment can be converted to a cyclic voltammetry dry lab. Students are provided cyclic voltammograms (data below) for a series of iron standards, and must construct a standard curve to determine the concentration of an unknown.
